how do I get locale code from language code in PHP

Basically I have a lot of language codes it, en, en-GB, de, de-CH, and so on... and from these I need to get a full locale code format: LANGCODE-COUNTRYCODE with the default country of the language if the country code is not already specified.

An example of what I mean/need:

INPUT      OUTPUT  

it     ->  it-IT  
it-IT  ->  it-IT  
en-GB  ->  en-GB  
en     ->  en-US  
es-AR  ->  es-AR   
es-MX  ->  es-MX 
es     ->  es-ES

is there any library I’m unaware of or a simple way of achieving this in PHP?

I’ve tried finding solutions on google a lot but either it doesn’t exist or I’m just using the wrong keywords…
Do I really have to make a manual array of this by hand? there must be a better way, I’m sure!

    The rules you describe in your follow-up comment are nothing but your subjective opinion about what countries are "more important" in regards of a given language. You pick Spain arguing Spanish is originally from there, but then pick United States for English (German is not mentioned, but it probably pre-dates Germany itself). You won’t find an algorithm for such ruleset, so there’s no other way than composing our own hard-coded list. Once you do that, the PHP portion can be as simple as an array lookup:

    $defaults = [
    'it' => 'it-IT',
    'en' => 'en-US',
    'es' => 'es-ES',
    // ...
];
$requests = [
    'it',
    'it-IT',
    'en-GB',
    'en',
    'es-AR',
    'es-MX',
    'es',
];
foreach ($requests as $input) {
    $output = $defaults[$input] ?? $input;
    echo "$input -> $outputn";
}
